Question

what are radionuclides how do they harm the environment​

Answer 1

Answer:

these cane from emissions of radio waves coming from uranium fission and fusions

Answer 2

Radium-226, Cesium-137, and Strontium-90 are examples of radionuclides. ... Every radionuclide emits radiation at its own specific rate, which is measured in terms of half-life. Radioactive half-life is the time required for half of the radioactive atoms present to decay.

Radionuclides that find their way into the environmental spheres may cause harmful effects as radioactive contamination. Furthermore, they can also represent an occupational health risk if not properly managed. Radiation may be released from electron excitation and emission.
